To all whom, it may concern:

Be it known that I, ARTHUR H. PORTER, a citizenof the United States,residing at Bristol, in the county of Hartford and State of Connecticut,have invented a new and useful Improvement in Clocks; and I do herebydeclare the following, when taken in connection with the accompanyingdrawings and the letters of reference marked thereon, to be a' full,clear, and exact description of the same, and which said drawingsconstitute part of this specification, and represent, in

Figure 1 a view in rear elevation of a clock constructed in accordancewith my invention. Fig. 2 a broken view thereof in vertical section.Fig. 3 a detail View showing the location of the bell-carrier within thecircular sheet-metal case-body. Fig. 4 a detached view of the annulardust guard. Fig. 5 a detail view on the broken line a b of Fig. 3showing how the case is reinforced by the bell-carrier and by the heavysheet-metal fastening straps which connect the movement with thecase-body.

My invention relates to an improvement in that class of portable clockshaving cylindrical sheet-metal cases and furnished with concentricallyarranged bells located at the back, the object of my present inventionbeing to produce a simple, compact and convenient clock constructed withparticular reference to improving the means employed for supporting thebell. and excluding dust from the movement.

In carrying out my invention as herein shown, I attach the concentricbell 2 by means of three screws 3 directly to the central'body-portion 4of a skeleton or spiderlike bell-carrier also comprising three radialarms 5 bent inwardly at an obtuse angle to the plane of the body-portion4 and terminating at their outer ends in fingers 6 arranged parallelwith each other and standing at a right angle to the plane of the saidbody-portion. These fingers are formed with perforations 7 for thereception of screws 8 passing through the cylindrical sheet-metalcase-body 9'with the sides of which the said fingers are parallel. Thebell 2 is thus carried solely by the bell-carrier which in turn iscarried solely by the case-body 9 which at the back opens directly intothe bell. I11 order to provide clearance room for the carrier whichprojects rearwardly'out of the case-body 9, I dispense with the usualdisk-like case back and employ an annular sheet-metal dust guard 10U-shaped in cross-section and adapted in diameter to be fitted into theback of the casebody 9 and to receive the edge of the bell 2 which onaccount of dispensing with the ordinary case-back is opened into at theback by the open case-body. The bell 2 and dustguard 10 together closethe case-body at the back and take the place of the ordinary sheet-metaldisk-like case back. The amount of dust that can work between the edgeof the bell 2 and the bottom of the guard 10 and through theperforations in the bell is negligible. As shown the bell is formed witha central perforation 11 for the hand-set 12, with a perforation 13 forthe alarm-set 141, and with perforations 15 and 16 for the rearwardpassage respectively of the stems employed for winding the time andalarm springs, these stems not being shown. As herein shown the ends ofthe fingers 6 are arranged in line with the feet 17 of the three heavysheet-metal fastening straps 18, 18 and 18 employed for securing theclockmovement to the case-body 9, the inner ends of these straps beingsecured to the front movement plate 19 and the dial 20 being secured tothe straps by fingers or clips 21. The movement is not shown beyond thesaid plate 19, the rear plate 22 and the pillars 23 and 24 it may be ofany approved construction.

If desired the fingers 7 may be abutted against the ends of the feet 9but this is not essential, though their arrangement in line is desirableas when thus arranged the said. lingers and feet greatly assist instiffening the sheet-metal case. By dispensing with the ordinarydisk-like case back and employing an annular dust-guard, I secure amplespace for the outward extension and vibration of the bell hammer whichis not shown. The strap 18 is secured to the case by a post 25 to whicha ring or handle 26 is attached, while the strap 18 and 18 are securedto the casebody 9 by the peg-like clock feet 27 and 28 which are ofordinary construction.

I claim:

1. In a clock, the combination with a cylindrical case-body open at theback, of a bell-carrier extended forward into the case body parallelwith the sides thereof and. directly attached thereto, and a bellarranged concentrically with the case-body and attached to theprojecting rear portion of the bell-carrier, the said case-body openingat the back directly into the said bell.

2. In a clock, the combination with a cylindrical case-body open at theback, of a bell-carrier extended forward into the casebody parallel withthe sides thereof and directly fastened thereto, a bell arrangedconcentrically with the case-body at the back thereof and secured to theprojecting rear portion of the bell-carrier, and a dust-guard applied tothe rear edge of the case-body and coacting with the bell in excludingthe dust from the case-body which opens at the back directly into thesaid bell.

3. In a clock, the combination with a cylindrical case-body open at theback, of a skeleton bell-carrier having radial arms terminating infingers extending forward parallel with the sides of the said case-bodyand secured directly to the inner face thereof, and a concentricallyarranged bell fastened to the said carrier which projects rearwardly outof rectly into the said bell.

4. In a clock, the combination with a cylindrical case-body open at theback, of abellcarrier itself carried by the said case-body a bellarranged concentrically with the casebody at the back thereof andfastened to the said carrier, and an annular dust-guard of U-shapedcross-section applied to the casebody and receiving the edge of the bellinto which the case-body opens at the back.

5. In a clock case, the combination with a cylindrical case-body open atthe back, of a clockn1ovement located therein, straps for securing themovement to the case-body, the said straps being formed with feet, abellcarrier located within the case-body and formed with fingersarranged in line with the said feet and secured directly to thecasebody, a bell arranged concentrically with the said case-body at theback thereof and attached to the said bell-carrier, and an annulardust-guard applied to the rear edge of the case-body and receiving theedge of the bell into which the case-body opens at the back.

In testimony whereof, I have signed this specification in the presenceof two subscrib- ARTHUR H. PORTER.
